Most reports from the United States suggest Culex quinquefasciatus mosquitoes feed minimally on humans. Given the abundance of C. quinquefasciatus in residential Tucson and parts of metropolitan Phoenix, and the arrival of West Nile virus to this area, discovering the blood meal hosts of the local population is important. Using a sandwich ELISA technique, the local C. quinquefasciatus were foun...

In the conditions of global climate change and invasion new diseases pests, utilisation local gene pool is a vital step towards sustainable agriculture. Local cultivars forms are generally considered as better adapted to originating region than widely spread commercial bred elsewhere. order collect, study, preserve old fruit vine forms, series expeditions have been conducted throughout Bulgaria...

Sustainable feed formulation (defined here as nutritional and economic feed optimization) is substantial in feed chain production from crop farmers to livestock producers. Diet formulation employing a static linear programming (LP) approach, which is widely used in trading firms and feed production facilities, does not allow for intertemporal flexibility. Our approach allows the interaction bet...

We propose a new computational model for the study of massive data processing. Our measures complexity reading input in terms their very large size N and analyzes cost parameter k that characterizes power provided by limited local computing resources. develop algorithmic techniques solving well-known problems on model. In particular, randomized algorithms running time O(N+g1(k)) space O(k2), wi...

This article reviews critical aspects of the aquafeed value chain in Kenyan aquaculture sector. Aquaculture production Kenya has grown steadily recent years, to more than 18,000 tons 2019. Due growing demand for fish and products, there been a gradual shift from extensive semi-intensive moderately intensive systems, leading an increased high quality commercial feeds. The current annual feed is ...

Introduction Feed costs comprise the majority of variable expenses in beef cattle systems making feed efficiency an important economic consideration within the beef industry (Koch et al ., 1963; Dickerson et al ., 1974) . Aside from the direct economic impact of this trait complex at the individual producer level, the projections of global population growth provide extra pressure for efficient ...
